PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

kubectl multi-version brews

We need to run multiple versions of kubectl for compatibility with various clusters.

It's a bit easier to get and use multiple versions of kubectl using Homebrew than it is using Macports.

With brew, it's simple to:

• Install a bunch of versions of kubectl (in the kubernetes-cli Formula)
• Switch between them as needed
